| Abstract: | Results of an indoor environment survey of 19 underground car parks in Hong Kong are reported. The indoor air temperature, relative humidity and air speed were measured. Subjective feelings of the occupants and their views on the indoor environment were surveyed by questionnaire. The design and operation of the installed ventilation systems and the number of occupants staying at the car parks were also investigated. It was found that studies of this kind are very important in providing design data. Further, a four-point assessment system is proposed to quantify the indoor thermal environment of the car parks. |
